what to do...

So Not too long ago, I bought some mixed frozen japanese veggies at the asian grocery store. The bag consists of mainly Lotus Root, SHiitake, Taro, and Gobo. The problem is...I have no idea what to do with them...I made a stirfry once but it didn't work out so well....I don't really care for frozen vegetables really, I usually only buy fresh lol I'm not really sure why i bought these...bleh but now i have to use them up haha...any ideas?
